隨著我國經濟的飛速發展，井蓋模具在城市規劃和道路建設中的市場需求量巨大.但是井蓋被碾壓而破損情況時有發生,導致道路及設施安全性下降.
With the rapid development of China's economy, the market demand of well cover mould in urban planning and road construction is huge. However, the damage of well cover caused by rolling often leads to the decrease of road and facilities safety

從各類井蓋標準談起,分析標準設置的合理性.是一種傳統的道路設備,一直在井蓋等方面占據主要地位,但近年來,隨著越來越多的新型材料的井蓋的設計生產
This paper analyzes the rationality of standard setting from various well cover standards. It is a kind of traditional road equipment, which has always occupied the main position in the well cover and other aspects. But in recent years, with the design and production of more and more new materials for well cover, the design and production of the standard are analyzed

水泥井蓋模具受到了前所未有的劇烈沖擊,其主要是由于水泥井蓋自身的一些缺點.水泥井蓋模具防盜效果好,但是缺點就是太笨重,而且要先制作水泥井蓋模具,施工后底座被混凝土固定,溝槽口封閉,只能使上蓋開合,而不能輕易拿掉.
The cement well cover has been subjected to unprecedented severe impact, which is mainly due to some shortcomings of the cement well cover itself.
